通用分页(Jquery版)

1、简单定义下样式

<style type="text/css">        .fanye        {            color: blue;            margin-right: 15px;            text-decoration: none;        }        .unUse        {            color: gray;        }    </style>


2、准备一个Div用来渲染分页按钮

<body>    <h1 id="result">        当前页码:[ 1 ]</h1>    <div id="pager">    </div></body>

3、编写分页功能

(function ($) {    $.fn.pager = function (options) {        var defaults = {            pageNum: 1,            pageCount: 1        };        var opts = $.extend(true, defaults, options);        //return this.each(function () {        return $(this).empty().append(renderPager(parseInt(opts.pageNum), parseInt(opts.pageCount), opts.btnCallback));        //});    };    function renderPager(pageNum, pageCount, btnCallback) {        var $pager = $(‘<div id="pageA"></div>‘);        $pager.append(renderBtn(‘首页‘, pageNum, pageCount, btnCallback)).append(renderBtn(‘上一页‘, pageNum, pageCount, btnCallback));        $pager.append(renderBtn(‘下一页‘, pageNum, pageCount, btnCallback)).append(renderBtn(‘尾页‘, pageNum, pageCount, btnCallback));        //$pager.append(‘<span></span>‘);        return $pager;    }    function renderBtn(btn, pageNum, pageCount, btnCallback) {        var $Button = $(‘<a href="javascript:;" class="fanye">‘ + btn + ‘</a>‘);        var currentPage = 1;        switch (btn) {            case "首页":                currentPage = 1;                break;            case "上一页":                currentPage = pageNum - 1;                break;            case "下一页":                currentPage = pageNum + 1;                break;            case "尾页":                currentPage = pageCount;                break;        }        if (btn == "首页" || btn == "上一页") {            pageNum <= 1 ? $Button.addClass("unUse") : $Button.click(function () { btnCallback(currentPage,pageCount); });        }        else {            pageNum >= pageCount ? $Button.addClass("unUse") : $Button.click(function () { btnCallback(currentPage, pageCount); });        }        return $Button;    }})(jQuery);


4、调用

<script type="text/javascript" language="javascript">        $(document).ready(function () {            var currentPage = 1;            var pageCount = 10;            pageBtnCallBack(currentPage, pageCount);        });        var pageBtnCallBack = function (currentPage, pageCount) {            $("#pager").pager({                pageNum: currentPage,                pageCount: pageCount,                btnCallback: pageBtnCallBack            });            $("#result").html("当前页码:[ " + currentPage + " ]");        };           </script>
